I've noticed cxwq and others thoroughly enjoy the AT3k... to have so many back-ups and such. I have an AT3k and still need to get some PETG for the barrels. Otherwise, it's in great shape. However, compared to my experience in in modding the AT2k, the barrels came off with much greater ease on the AT2k. In fact, I could slide them out, take out the air-restrictors and replace the stock barrels without the restrictor without side effects. I have an AT4k on the way in the mail, and so here you're to the point where all of this rambling is going. My question is, does anyone know how easily the AT4k barrels come off? Can I expect to fight it every step of the way like the AT3k where you almost have to use a saw perforce, or can one just slide them out the way one can the SM3k or AT2k barrels and just slide them back in? In a related question, why do you laud the AT3k so much, cxwq as to have so many back ups? Or anyone else who knows of any distinctions? What are the drawbacks to the doubled ammo count of the AT4k? Thanks.

An at3k is awesome because of its great ROF, and it's power and accuracy, and it's not-to-big size. The thing you have to keep in mind is: the more barrels, the more air loss. At4k is not too bad, but if you're looking for something that is machinegun like, try a rapidfire 20 or a wildfire, or a power clip.

I have a powerclip, rapid 20, etc. I was under the impression that the AT3k had the same function as the SM3k or AT3k or AT2k, meaning that you pump, rotate, fire, repeat. Are you trying to imply it's an automatic weapon when you speak of air loss?

I don't have a 4k so I can't compare the two directly. I heard that it's easier to pump the 3k so I stuck with that. 6 shots is enough for me as I generally find ten seconds of down time every few shots during a war and fill up my empty barrels.

I think the 3k is good enough to justify my stock because it's the only gun I've ever used in a war that is flexible enough to do whatever I require of it. I've played in a CTF game where I was sitting 20' forward of my flag, took out two rushers, then immediately afterwards as my guy grabbed their flag I was able to move forward and clear a path for him. Having 6 accurate shots that I can get off in under 20 seconds is just a huge tactical advantage.

That said, the 4k is probably similarly cool.


Edit: You are correct, the at3k is pump (auto rotate), fire, repeat not full auto.

Thanks guys. I would like to point out that we all rock with our immediate and cogent replies to threads. I'll let you know how things work out once I pick up some PETG and the AT4k arrives. :lol:

When you open up the rotating barrel part, you can see an tiny air gap between the air tank, and the barrels. This leaves room for small air loss. Of course, it's not very evident, as you can get 80 feet from an at3k easily. With more barrels, there is a bigger air loss. 4 barreled supermaxxes can get ranges of up to the 90s, and single barreled (this way they are airtight) definately 100+. The airtech 3000 is just a very versatile weapon. One reason you may not like the sm3k is because of it's massive size. Also, I've heard that the sm3k sometime's is unreliable when it comes to the turning. And - at3k looks cooler. :lol:

Although i've never own3d (er...owned) an AT3K, i can tell you the AT4K sucks, big time. From the pictures it would seem that the AT4K air chamber is about half the size of the 3K. Cwxq was right, the 3K is probably easier to pump. Hell, i can probably pump my 2k to max easier that i can pump the 4k at all! The pump is huge, and the airchamber is small, so i assume that it was meant for one pump per shot. Besides, AT4K isn't worth single-ing, for reasons i said before. Looks wise, i'd say the AT4K looks better, but thats just me.

Aw, come on! That's why I like it!

mine hasn't ever skipped on me, and eight shots in about seven seconds while still being accurate,and having an average range of 65-70', (holding it naturally) can beat out a whole bunch of guns, including in my opinion, an At3K. I use my AT2K as a sidearm to the SM3K, a tribute to it's usefulness. :blink:

But that's just me.

My copper modded SM3k is outshooting my crayola AT3k constantly. I'd say SM3k ranges are somewhere between 70 and 100. I don't measure often, but Tinkerer's estimates don't seem so bad. I use stock micros. The biggest problem is that if I pump the SM3k more than once, there's so much power that the accuracy goes out the window and the dart might go awry, at least with my stock ammo. Anyway, the copper seems to make the AT3k too heavy to rotate properly, but it'd probably be about the same as the SM3k in terms of distance if I could get the copper to work properly on it, or so I assume. I haven't looked at the SM3k airtank but I suppose they're about the same size.

Crankymonky

If you're referring to my pvc mod, that was 100' at an angle

If you're referring to my 10" E-Z pipe barrel mod, that was with four pumps (and risking the detonation of the gun might I add)

I cut the barrels down to five inches, and stopped pumping more than once. (on the advice of a few nerf veterans) so now those are the ranges I get.

I don't know, I like my AT3K more than my SM3K, or, when I had an SM3K. Now only the case is left. The valve on my SM3K blew. I lent it out and someone snapped the metal rod clear out of the valve plug.

I have modded my AT3K with: single breechloaded paperboard barrel (10" long, 17/32" ID), replacement of goo tube and the original tubing with 10" of 1/4" OD tubing, release valve plugged, and a 1/2x3/4" PVC sight with paperclip crosshairs. I pump it five times, and when the trigger actually fires it, the darts go over 100'. I would say that the AT3K is better than the SM3K and AT4K in size, weight, accuracy, and distance. That all depends on how they are modded though.

I own two AT3ks, a Supermaxx 2500 (larami), a sm3k, and an at4k. The 4k has got to be one of the most difficult guns to pump that I've ever used; Because of the position of the pump, its extremely uncomfortable and very hard to use. Having no petg, and because the 4k has 12 barrels, it would no longer rotate if I were to multibarrel it. Instead i removed the rotating device, and thought i might be able to get some results out of single-ing it. Wrong. The 4k also has a very small airtank, and I could never get it to fire past 50 feet. The AT3Ks have been alright, but I've never gotten as good as results as everyone else. Mine consistantly hit 60, but will never go further, thats ok though, because its multibarreled. I used to have two sm3ks, but I over pumped the modded one, so now I have one that im working on, but currently is unmodded. The one that I sucsesfuly mod (before it broke) used to get around 70 foot ranges (blue sm3k). The Larami 2500 I have is excellent, but recently stopped firing (I think the trigger has just come off its tracks); however, before this happened it used to get much better ranges than my sm3k, though I never officially mesured it, it probably fired 80 or more feet. I find the Sm3k and Larami 2500 much, much easier to pump than the AT3k or 4k, especially the 2500, though the at3k isnt that bad. On size and accuracy, I think the AT3k and SM3k/2500 are about the same accuracy wise; as for size, although the 2500 is bigger, I find it extremely comfortable, the 3k is not quite as comfy, and because of the large diamiter pump tube it feels like its going to crack in half every time I pump it, and the AT3k is not bad, but I always feel like its almost too small, the small pump handle makes it feel as if there is much more resistance compared to the 2500.

The pressure gets high enough that the spring will be fully compressed when the trigger is pulled, yet the valve plug won't be pulled. I solved that with minor modding. Now comes the funny: when my AT3K is pumped 5-6 times, my friend, his brothers, and my dad cannot pull the trigger. It's as if they have no finger strength. Interesting. My trigger is now starting to have damage from stress, but the tubing inside the gun has yet to crack or leak.

But that's just me.

Heehee, I guess that IS a good reason to like a gun...

Anyway, regarding the supermaxx3k, I guess it wasn't really my position to say "it's not as good" because people have their own preferences. One of my friends owns a sm3k and it sucks like crap, and DOES miss turns ^_^ . I guess that's just his: More power to ya if yours is awesome.

Yeah, Namm's explanation would be WHY I'm changing my mind. My person preference is smaller guns so that I can move around easier, and move my guns around easier. But that's just me.

So the AT4k finally came today. I sawed off the barrels and noticed some looked wider than others. There were parts of the original air restrictors fused to the barrels because of the saw in most of the barrels... a dremel, a thin wedge and hammer and pliers later (the dremel would flatten out what was left of the air restrictor bottom so it could be pulled out), all the barrels were nicely wide enough for crayolas to slide evenly (we all use stock ammo at my indoor games at school). Compared to the AT3k, it's about the same in range. To answer my own original question, the AT4k air restrictors are even more difficult to break out than those of the AT3k. The pump handle is so small that right out of the package I cut my finger just innocently pumping the gun, so there's an advantage for the AT3k. I took a turn signaler I sledgehammered out of a car and ducttaped that sucker on for better pumping. The crayolas work nice and the range is comparable to the AT3k. The drawback apart from size is that damned handle. Additionally, after putting the gun back together, I had some trouble getting the rotator to work. it seemed that little round thing on the airtank release rod that preps the rotator to get ready for a second, third, etc. shot wasn't as far back as it should've been, i.e. the trigger rod was slightly loose. Duct tape near the airtank stopped it from sliding forward and backward. That wasn't the end of my rotator trouble though. After playing with the inernals for a long time, I couldn't figure out what the other problem was. Basically, half the time the gun would pump fine, the other half it would keep rotating an additional barrel for each additional pump, but not even consistently. I went to that spring that wraps around the rotator near the plastic bit that moves up and down (if you've never been inside an AT4k, you have no idea what I'm talking about) and pulled it out of it's secure hole on the far side; assuming the rotator was somehow stronger than it needed to be. I was correct and the twelve shot crayola mod is firing nicely. While it's nice to have the extra six shots, my finger is still afraid of being bitten by the pump handle again. Either way, these crayola mods aren't getting the range of the blue SM3k copper mod I did. The AT3k and AT4k, at least in my cases, don't support metal mods due to the limits of rotator strength. So much easier with the SM3k. I didn't even have to open the gun, just pop off the cap, pull out the oversized barrels, duct tape the copper, shove it in, voila. Even took some 3D glasses, cut off the blue side and put that on a flashlight I shoved where the cap used to be.

Conclusion: SM3k still my favored for insane distance, easy mod and minimal pumping, but the higher ammo for a minimal range sacrifice for the AT4k and the same range of the AT4k for the wonderful feel and size of the AT3k make variety my friend.

You can achieve ranges like that with only one pump?
